SPECIFICATION forming part of Letters Patent No. 558,556, dated April21, 1896.

Application tiled October 4,1895. Serial No. 564,590. (No model.)

T0 all whom, it may concern:

Be it known that LWILLIAM L. HAAG, a citizen of the United States, and aresident of Lansing, in the county of Ingham and State of Michigan, haveinvented new and useful Improvements in Sleighs; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention is related to that class of sleighs termed bobesleighs orcarriagerunners.7 Its object is to connect the bolster or carriage-axleto the knee of the sleigh by a clamp solidly attached to the bolster oraxle and movable on the knee instead of a clamp which is a part of theknee and movable on the axle.

It consists of a knee so constructed that it forms a semicircular restfor the bolster,which has a clamp solidly attached to it, through whichthe curved portion of the knee passes, and in which it moves forward orbackward as the runner is thrown up or down in passing over theinequalities of the road, and in the peculiar construction andarrangement of the several parts, as hereinafter more particularly setforth and claimed.

Figure 1 is a perspective view of my sleighknee or carriage-runner. Fig.2 is a section through the upper part of the knee and the bolster on theline a; :c in Fig. 1. Fig. 3 is a section through the support of theouter end of the bolster on the line fy g/ in Fig. l. Fig. 4t is aperspective view of the semicylindrical block attached to the under sideof the bolster. Fig. 5 is a perspective view of the retaining-block onthe under side of the semicircular top of the knee, showing the recessfor the knee and for the block attached to the bolster. Fig. 6 is a planview of the retaining-block, showing the block on the under side of thebolster resting on its recess.

In the drawings, A represents the runner provided with the usual shoe a.

A is a brace or rave connected to the front end of the runner andextending back to the front leg of the knee, to which it is securelyriveted or bolted.

B B are the front and back legs of the knees some distance apart on therunners, inclined toward each other, so as to be but a short distanceapart at the top. These legs are prolonged in the feet b b, providedwith iianges to embrace the runner, and are securely fastened to therunner by bolts passing through the feet b Z9 and the runner and shoe.

B is a bar of the same width as the knee, fastened at its central pointto the runner, at the middle point between two feet of the knee, havingits two ends turned upward as braces to the two legs B B of the knee towhich they are firmly riveted. This construction makes the knee strongenough to carry a heavy burden and to resist great strain either forwardor backward.

The upper or central part of the knee is bent downward between the twolegs in a semicircle to form the curve B2, on which the axle or bolsterC rocks.

D is a semicylindrical block fastened to the under side of the axle orbolster C near its outer end. The axle or bolster is of the ordinaryconstruction, except the block D ,which takes the place of the usualbearing for the hub. The upper or flat face of the block D is in contactwith the axle and the rounded or lower face bearing on the curved partB2 of the knee.

Recesses d d d d are cut in the block D at each of its fourcorners,forming the shoulders d d d d' and d? d2 cpd?. These shouldersrest against the bolts e on the clips E, which pass through the recessesd and the perforations f5 in the retaining -block under the curved topof the knees.

The arms or projections di cl3 on the block D are flat on their underside with square ends and rest on a flat shoulder at the end of therecess f in the retaining-block F and against the wall or end of therecess.

The arms or projections d4 d4 do not entirely cover the sides of thecurved recess f, but leave an opening between the bearingblock D and theretaining-block F for the reception of the curved top B2 of the knee,which supports the axle or bolster.

F is the retaining-block under the curved top B2 of the knee attached tothe axle or bolster by the bolts e at the ends of the clips E,passingthrough the perforationsf. A con- IOO cave recess f is formed in theupper side of the block, having the same curvature as the under side ofthe semicircular top of the knee. At the ends of this recess a curvedledge or shoulder f2 is cut, having the same curvature as the under sideof the bearing-block D, which rests upon it, leaving a space or openingbetween the under side of the bearingbloek and the concave recess f ofthe proper size and form to receive the curved top B2 of the knee. Thedotted outline of the upper part of the knee in Fig. 2 of the drawingsshows the extent of the play of the knee on the axle or bolster.

Another shoulder f3 is cut above the shoulder f2 in both ends of therecess, having a iiat straight surface and side for reception of the armcl3 cl3 of the bearing-block D. The end walls of the recess f, engagingwith the ends of the bearing-block D, prevent any lateral play of theknee on the axle or bolster.

Gis a semieylindrical block or saddle on the top of the axle for thepurpose of obtaining a longer bearing for the clips E, which straddlethe block and axle, and the ends pass down through the recesses d CZ onthe bearing-block and the perforations]c5 through the block F, wherethey are secured by screws and nuts. lt is evident that this block G maybe entirely omitted if the bolster is large enough to afford suflieientbearing for the clips.

H I-I are two braces or arms projecting outward from the lower part ofthe front and back legs of the knee and inclining toward each other atabout the same inclination as the inclination of the legs of the knees.The

downwardly-projecting curved plate 7L and the flat plate 7L above thecurved plate h are firmly attached to the outer upper ends of the arms HH in a horizontal position by bolts or rivets. These two plates form asemitubular socket, having its axis in a straight line with the axis ofthe bolster or axle of the sleigh. The outer end of the axle or bolsterC is rounded to engage with this socket, and is provided with the collarC to prevent end play of the socket on the axle. These braces or armsthus connected with the outer end of the axle or bolster prevent anylateral motion of the runner either inwardly or outwardly, while leavingit free to work backward or forward as it passes over the inequalitiesof the road.

That I claim as my invention is- 1. The combination of a sleigh-knee,having a downwardly-curved upper end, with a block through which thedownwardly-curved upper end of the knee passes firmly attached to thebolster, and the bolster above the knee, all substantially as described.

2. The combination of the downwardlycurved upper portion B2, of theknee, with the retaining-block E, through which the downwardly-curvedportion of the knee passes irmly attached to the bolster, and thebolster above the knee, all substantially as described.

3. The combination of the knee having a curved top which rocks on thebolster, the bolster convex on its lower side to rest on the curved topof the knee, and the retainingblock through which the curved top of theknee passes iirnily attached to the bolster, all substantially asdescribed.

4E. The combination of the knee having a curved upper end with a bolsterresting on the curved upper end of the knee, a retaining-block under thecurved part of the knee iirmly attached to the bolster, the armsextending froin the knee supporting the socket, and the socket for thereception of the end of the bolster, all substantially as described.
